E-911 service providers

E-911 service providers provide routing of emergency calls from Lync to the correct emergency dispatch center responsible for deploying emergency responders for the given client location. Enterprises can use E-911 services to provide location-aware emergency dialing support for both hard phones and soft phones. Emergency calls using E-911 service providers are delivered exclusively over SIP trunking connections to the service provider, including the location information directly in the call.
